[agtk-devel] Spec for discontinuous annotation

[Nikhil D. <ni...@se...>]

Hi,

Im trying to integrate annotations for the Penn Treebank and the
Discourse Treebank. The discourse annotations have discontinuities in
them. For example consider:

John left the party because he was tired. He returned later however
after having rested awhile.

"however" is a connective potentially relating the propositions:
a. John left the party
b. [He returned later] [after having rested awhile.]

Similarly "because" is a connective relating:
a. John left the party
b. he was tired

More abstractly the arguments are multiple partially-overlapping
discontinuous spans of text and I was wondering:

a. What is the ag recommendation for such spans? There seem to be
may ways to go about it.

b. How does ag represent syntactic traces? As self-loops?

c. If I do convert it to the spec, is there a display and query part
of the toolkit that would work on it?

Also I couldnt get at the DTD from the website.

Thanks,
Nikhil.
